WITH ERECT IMAGE IN P.V.C BOX AND ALUMINIUM FOLDING STAND

When cathode rays are focussed on wax coated on the outside of the upper round head of cathode ray tube, the wax melts quickly showing heat generated by cathode rays.

WITH ERECT IMAGE ALUMINIUM STAND

WITH ERECT IMAGE IN WOODEN BOX AND ALIMINIUM FOLDING STAND

20 cms. SET OF 6, in wooden polished showcase with rotary switch for connections to each tube.

Consists of two units, each mounted on a plastic base which can be clamped to a 12 mm diam. retort stand rod. The solenoid unit ensures prompt release of a metal sphere on de-energising. The gate switch unit comprises a hinged steel plate held against an adjustable contact by a small magnet so that by proper adjustment, the plate falls promptly as soon as the falling sphere falls on it. Complete with stand.

Four stroke water cooled diesel engine, shows functioning of fuel injection system together with hot coil starting device.

For verifying laws of composition and resolution of forces, comprising a machined aluminium table 40 cm diam., scale graduated 360°, on heavy vertical support rod and tripod base. Complete with one ring, 4 sliding clamp pulleys. Supplied with four cords with rings at one end, without masses.

2 METER RIGID
